Spatially Varying Transform with Adaptive Transform Type - A simplified explanation of the abstract
This abstract first appeared for US patent application 18166890 titled 'Spatially Varying Transform with Adaptive Transform Type
Simplified Explanation
The video decoding method described in this patent application involves determining the usage of an SVT-vertical (V) or an SVT-horizontal (H) for a residual block. It also includes determining the position of a transform block within the residual block and the type of transform to be applied to the block. The transform type can be a combination of horizontal and vertical transforms, with at least one of them being a discrete sine transform (DST)-7. Finally, the method involves reconstructing the residual block based on the transform type, transform block position, and transform coefficients.
- The method determines whether to use SVT-vertical or SVT-horizontal for a residual block.
- It determines the position of a transform block within the residual block.
- The method specifies the type of transform to be applied, which can include a combination of horizontal and vertical transforms.
- At least one of the transforms used is a discrete sine transform (DST)-7.
- The method reconstructs the residual block based on the determined transform type, transform block position, and transform coefficients.

Original Abstract Submitted
A video decoding method includes determining a usage of an SVT- vertical (V) or an SVT-horizontal (H) for a residual block; determining a transform block position of a transform block of the residual block; determining a transform type of the transform block, wherein the transform type indicates a horizontal transform and a vertical transform for the transform block, wherein at least one of the horizontal transform or the vertical transform is a discrete sine transform (DST)-7; and reconstructing the residual block based on the transform type, the transform block position, and transform coefficients of the transform block.
